The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-201206-15 (libpng: Multiple vulnerabilities)

Multiple vulnerabilities have been discovered in libpng:
The “embedded_profile_len()” function in pngwutil.c does not check for negative values, resulting in a memory leak (CVE-2009-5063).
The “png_format_buffer()” function in pngerror.c contains an off-by-one error (CVE-2011-2501).
The “png_rgb_to_gray()” function in pngrtran.c contains an integer overflow error (CVE-2011-2690).
The “png_err()” function in pngerror.c contains a NULL pointer dereference error (CVE-2011-2691).
The “png_handle_sCAL()” function in pngrutil.c improperly handles malformed sCAL chunks(CVE-2011-2692).
The “png_decompress_chunk()” function in pngrutil.c contains an integer overflow error (CVE-2011-3026).
The “png_inflate()” function in pngrutil.c contains and out of bounds error (CVE-2011-3045).
The “png_set_text_2()” function in pngset.c contains an error which could result in memory corruption (CVE-2011-3048).
The “png_formatted_warning()” function in pngerror.c contains an off-by-one error (CVE-2011-3464).
Impact :

An attacker could exploit these vulnerabilities to execute arbitrary code with the permissions of the user running the vulnerable program, which could be the root user, or to cause programs linked against the library to crash.
Workaround :

There is no known workaround at this time.

Solution

All libpng 1.5 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/libpng-1.5.10' All libpng 1.2 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/libpng-1.2.49' Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
